Overview
AVILA wastewater treatment plant serves Ávila, Castilla y León, Spain, with a population equivalent of 250,000. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The AVILA wastewater treatment plant is located in Ávila, in the autonomous community of Castilla y León, Spain. Serving a population equivalent of 250,000, it is classified as a large agglomeration under EU regulations. The plant is situated near the Adaja River, which flows through the Duero basin. As a facility serving over 150,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment and, in sensitive areas, tertiary treatment for nutrient removal. The regulatory framework ensures compliance with discharge standards. The treated effluent is discharged into the Adaja River, a tributary of the Duero River, which ultimately flows into the Atlantic Ocean near Porto, Portugal. The Duero basin supports diverse aquatic life and is an important ecological corridor in the Iberian Peninsula. The plant's operations help protect water quality in this transboundary river system.
Environmental context
The AVILA plant discharges into the Adaja River, a tributary of the Duero River. The Duero basin is a major hydrological system in Spain and Portugal, supporting irrigated agriculture and diverse freshwater ecosystems. Downstream, the river flows through the Arribes del Duero Natural Park before reaching the Atlantic Ocean. The plant's nutrient removal helps prevent eutrophication in this sensitive river basin.
